There are two things that go into any creative project - money and time. You finish your piece of art when you run out of money or time. For this to happen, you have to have a strict deadline and a budget.

The deadline is important, otherwise you could perfect the work forever. When you pass the deadline - you stop working on the project, stop worrying about it and let the world decide if your piece of art will live or die.

The budget is crucial, too because if you work beyond the financial boundaries, you could go broke.

If you remember your deadline and the budget, your artwork might have a chance to live on its own.
